Claims (8)

  1. Réseau local, en particulier pour véhicule, comprenant au moins un maître (10) et plusieurs esclaves (Ai, Bi), qui peuvent être pilotés par le maître (10) via un bus de données (12), dans lequel au moins un esclave (Ai) est agencé dans une zone protégée (A), par exemple à l'intérieur du véhicule, et au moins un esclave (Bi) est agencé dans une zone non protégée (B), par exemple à l'extérieur sur le véhicule,
    caractérisée en ce que
    le maître (10) est couplé via deux émetteurs-récepteurs (14,16) avec les esclaves (Ai, Bi) de telle façon que des données qui proviennent d'un esclave respectif (Bi) dans la zone non protégée (B) sont transmissibles certes vers le maître (10), mais non pas vers un quelconque esclave (Ai) dans la zone protégée (A), dans lequel une sortie de données (18) du maître (10) est reliée à une entrée de données (TxD1) de l'un des émetteurs-récepteurs (14) couplée directement à l'esclave ou aux esclaves (Ai) dans la zone protégée (A), une sortie de données (Rx D1) de cet émetteur-récepteur (14) est reliée à une entrée de données (TxD2) de l'autre émetteur-récepteur (16) couplée directement à l'esclave ou aux esclaves (Bi) dans la zone non protégée (B), et une sortie de données (RxD2) de cet émetteur-récepteur (16) est reliée à une entrée de données (20) de l'appareil maître (10), lequel retransmet directement avec l'émetteur-récepteur (14) couplé directement à l'esclave ou aux esclaves (Ai) dans la zone protégée (A) les données émises par le maître (10) et reçues à son entrée de données concernée (TxD1) vers le ou les esclaves (Ai) dans la zone protégée (A), de sorte que via la sortie de données concernée (RxD1) de cet émetteur-récepteur (14), aussi bien les données émises depuis le maître (10) que les signaux de réponse de l'esclave ou des esclaves (Ai) agencés dans la zone protégée (A) sont transmissibles à l'entrée de données concernées (TxD2) de l'autre émetteur-récepteur (16) couplé à l'esclave ou aux esclaves (Bi) dans la zone non protégée (B), cet autre émetteur-récepteur transmettant ces données à l'esclave ou aux esclaves (Bi) dans la zone non protégée et, via la sortie de données concernée (RxD2) de cet émetteur-récepteur (16), les signaux de réponse de la totalité des esclaves (Ai, B eti) sont transmissibles à l'entrée de données concernées (20) du maître (10).
  2. Réseau local selon la revendication 1,
    caractérisé en ce que le maître (10) est couplé via les deux émetteurs-récepteurs (14, 16) avec les esclaves (Ai, Bi) de telle manière que, indépendamment de savoir si un esclave respectif (Ai, Bi) est agencé dans une zone protégée ou une zone non protégée (A ou B), entre l'esclave (Ai, Bi) et le maître (10) une circulation des données bidirectionnelle est à chaque fois possible.
  3. Réseau local selon la revendication 1 ou 2,
    caractérisé en ce que les deux émetteurs-récepteurs (14,16) sont reliés l'un à l'autre de telle façon que des données partant d'un esclave respectif (Ai) dans la zone protégée (A) peuvent être transmises à un esclave quelconque (Bi) dans la plage non protégée, alors qu'un flux de données partant d'un esclave respectif (Bi) dans la zone non protégée (B) vers un esclave quelconque (Ai) dans la zone protégée (A) est exclu.
  4. Réseau local selon l'une des revendications précédentes,
    caractérisé en ce que les deux émetteurs-récepteurs (14, 16) sont reliés au maître (10) via seulement une interface série (22).
  5. Réseau local selon la revendication 5, caractérisé en ce que le maître (10) comprend au moins un microcontrôleur (24), et l'interface série est associée au microcontrôleur (24).
  6. Réseau local selon l'une des revendications précédentes, caractérisé en ce que le bus de données (12) est un système de bus monofilaire.
  7. Réseau local selon l'une des revendications précédentes, caractérisé en ce que l'on prévoit comme bus de données (18) un bus de données LIN (réseau interconnecté local).
  8. Réseau local selon la revendication 7, caractérisé en ce que les deux émetteurs-récepteurs (14, 16) sont réalisés à titre d'émetteurs-récepteurs de LIN.
